What does CNC technology mean?

"CNC" technology is "Computer Numerical Control", CNC technology refers to the use of special computers and interface circuits, which can be used to realize the control of the movements of multiple numerical control equipment.

This technology uses a computer to perform the control function of the equipment according to the control program stored in advance. As a result of the use of computers to replace the original hardware logic circuits composed of numerical control devices, so that the input data storage, processing, arithmetic, logic judgment and other control functions can be achieved through computer software to complete.

Numerical control technology is the use of digital information on mechanical movement and work process control technology, numerical control equipment is represented by numerical control technology on behalf of the new technology of the traditional manufacturing industry and the new manufacturing industry penetration of the formation of electromechanical integration products, that is, the so-called digital equipment, such as CNC machine tools.

Extended information:

Traditional machining are manually operated ordinary machine tool operations, processing by hand to shake the mechanical tool to cut metal, rely on the eyes of calipers and other tools to measure the accuracy of the product. tools to measure the accuracy of the product. Modern industry has long been the use of computerized digital control of machine tools for operations, CNC machine tools can be programmed in accordance with the technicians in advance automatically on any product and parts directly for processing.

This is "CNC machining". CNC machining is widely used in all mechanical processing in any field, but also the development trend of mold processing and important and necessary technical means.

Numerical control machine tool is in accordance with the pre-programmed processing program, automatically processed parts. We put the parts of the machining process route, process parameters, tool trajectory, displacement, cutting parameters (spindle speed, feed, back eating amount, etc.) and auxiliary functions (tool change, spindle forward, reverse, cutting fluid on, off, etc.).

In accordance with the CNC machine tool instruction code and program format written into a machining program list, and then the contents of this program list recorded on the control media (such as perforated paper tape, magnetic tape, magnetic disk, magnetic bubble memory), and then input to the CNC machine tool numerical control device, so as to command the machine tool to process parts.

Because the CNC machine tool has to process the parts according to the program, the programmer prepares the program and inputs it into the CNC device to command the machine tool to work. The input of the program comes through the control medium.
